Rather than comparing entity handles, you can simply use ssmemb, e.g.: (defun subtract_ss ( ss1 ss2 / ent idx ) (repeat (setq idx (sslength ss1)) (setq idx (1- idx) ent (ssname ss1 idx) ) (if (ssmemb ent ss2) (ssdel ent ss1)) ) ss1 ) Or, alternatively - (defun subtract_ss ( ss1 ss2 ) (vl-cmdf "_.select" ss1 "_r" ss2 "") (ssget "_p") )3 points

Thank you both for the quick response. I ended up using Lee's second function and it works like a charm. Much appreciated.1 point
